Designing And Empoldering Of Elite Dairy Cattle Register And Individual Mating PDA System

Prerequisite for dairy offspring hereditary character improved and cow herd gene frequency changed was the work of dairy cattle breed selection and individual planned mating. Individual planned mating work of dairy cattle is one of effective methods to guarantee carrying on of dairy breeding work. With the development of electronic information technology and microelectronics technology, dairy cattle Breeding electronic equipment have come into being and the developed countries of the cow industry mostly practiced palmtop computer to foster the national excellent dairy herds by type linear classification of dairy cattle and planned mating.At present, cow individual planned mating was lack of the portable electronic equipment in Heilongjian. A lot of questions exist in such respects as accuracy and efficiency of cow individual planned mating. These questions have directly influenced the development of the cow industry in our province.For this reason, combing the advanced experience of PDA abroad and"Elite cow register system", we have developed"Elite dairy cattle register and individual planned mating PDA Decision System", which could collect data and register in dairy farm, score for cow type, provide individual planned mating program to achieve mobile office, and promote the work of the cow breeding digital more quickly and effectively.To embedded computer technology at the core of the PDA (Personal Digital Assistant) technology has been widely applied to many fields. In order to enable the development of PDA devices with easy, real-time, and high stability and user-friendly easy-to-use conditions, the study choices based on Windows CE development platform. Development of improved procedures for registration of the original software used by VB.NET converted to C #, C # excellent compatibility can be more convenient to the software embedded PC to PDA, so as to streamline the development process.This system includes two parts mainly (PDA software support system and individual planned mating PDA system):PDA software support system: The system included basic database of dairy cattle, database of dairy cattle heredity evaluation, elite cow register, and module of internet data transmission .It can offer begat information, and individual planned mating, report of heredity evaluating, and report of heredity evolution forecast etc. In addition, data exchange between PDA and cow breeding system was achieved by data communications middleware, and the software build information plat for establishing PDA technology.There were three functions of the PDA system:1. Collecting, input and enquiry of dairy cattle basic data in dairy farm: It is used for registering cow basic information, pedigree, progeny records, growth and developmental condition, historical and current production performance, historical and current reproduction performance, and childbirth. Windows of classification collection and input were established through corresponding individual cows and the composition of the database structure. Enquiries into fuzzy and precise query: production, progeny and address were included in fuzzy query and the numbers of dairy cattle in precise query.2. Type linear classification of dairy cattle of dairy cattle was scored according to the Canadian 9 points standard in dairy farm: the PDA software system included field investigation modules, linear classification modules and rating modules of body type and appearance. The integration scores of body type and appearance were given automatically through three score modules.3. Function of individual planned mating: PDA software was tested by the collected data and dairy cattle in Xing-Huo farm of Da-Qing were chosen as individuals matching objects. The previous ten bulls whose inbreeding coefficient with cow is less than 4% were selected after pedigree information of dairy cattle was pull out, the individual planned mating was given by PDA automatically after the improved standard was input. The function could prevent inbreeding and enhance the effectiveness of improvement.The data will be reserved and computed in the PDA software support system of the PC by middleware after information acquisition, the fieldwork and office system software were combined as well the effectiveness and accuracy of breeding improvement were enhanced.
